Influence of Tytanit application on the chemical composition of root zone of tomato growing in rockwool

Summary.

The aim of the conducted studies was estimation of the influence of titanium fertigation application on the changes of chemical composition in root zone of tomato growing in rockwool (control – without dose of Tytanit, Ti-I – yearly dose 2.01 mg Ti per plant, Ti-II – 6.04 mg Ti per plant, Ti-III – 12.08 mg Ti per plant, Ti-IV – 24.16 mg Ti per plant). The changes of nutrients contents, salinity and pH in plants’ root zone were typical for growing of that species. Generally there was no significant influence of titanium on the chemical composition of standard nutrient solution used to tomato fertigation. Research shows that while using nutrient solution fertigation of tomato supplemented with titanium there is no need to interfere with the chemical composition of standard solution used for the cultivation of tomato in rockwool.
